Abstract: To study the distribution law of random unbalance response of multistage blower, a kind of random emulation experiment method was brought forward, of which the principle is using the simulated values of random unbalance variables generated by computer, through a large number of emulation experiments and statistical analyses, to draw a conclusion about the distribution law of the vibration type and amplitude. Using this method, the study result of D900 blower of a metallurgical factory showed that the vibration types of blower are mainly the first order vibration type, so it is practical to apply auto-balance technology; the figure of the distribution law of the blower’s amplitude by statistics was also obtained, therefore a series of statistical parameters such as maximum amplitude, average amplitude were defined, which have reference value in some degree to guide the blower equipment’s working condition diagnosis and service action management.
